Passage Retrieval API enhances accuracy, relevance, and security, reducing hallucinations and protecting sensitive data for smarter, more reliable GenAI applications

Proven with global enterprises, new Passage Retrieval API accelerates time-to-value with industry-leading retrieval

Coveo, the market leader in AI-Relevance delivering AI-search, generative, and business-aware relevance at every point-of-experience, announced that the Coveo Passage Retrieval API, a headless retrieval method for generative AI applications that leverages the Coveo’s best-of-breed AI-Relevance Platform^TM, is now generally available.

Coveo’s Passage Retrieval API: Strategic and critical for enterprises’ GenAI success

“Enterprises today are challenged with turning vast amounts of fragmented data into accessible and relevant knowledge for generative and conversational AI,” said Laurent Simoneau, Co-Founder, President and CTO at Coveo. “While large language models (LLMs) hold immense potential, their success hinges entirely on the quality of the data they access—a growing concern as many enterprises develop their own GenAI applications. Many organizations are adopting Retrieval-Augmented Generation (RAG) and quickly realizing that the hardest part—the ‘R’—lies in retrieving precise and relevant information from scattered enterprise systems. This critical step ensures secure, accurate, and relevant AI responses, yet its complexity often hinders progress.”

Coveo’s Passage Retrieval API directly addresses this challenge by delivering precise, trustworthy text to LLMs and AI applications, including Salesforce Agentforce, Microsoft Copilot, Amazon Bedrock Agents, and SAP Joule. The API boosts accuracy, minimizes hallucinations, and meets enterprise security requirements, all while improving deployment speed and reducing costs. Organizations can, therefore, consistently scale multiple generative AI applications using a single, reliable retrieval method.

A Unified Index for All Your GenAI Needs

With Coveo’s proven information retrieval method and advanced relevancy and ranking techniques now available to power generative AI applications, organizations can ground results in enterprise knowledge with greater efficiency and significantly accelerate time-to-value. Coveo’s platform centers on an industry-leading unified index that combines advanced ranking techniques—lexical, vector-based, and behavioral—to securely connect data from systems like CRMs, ERPs, ITSMs, and CMSs using prebuilt connectors. This eliminates redundant indexing and integration work, cutting maintenance costs while supporting a wide range of AI applications such as search, recommendations, generative AI and content discovery.

Designed to scale seamlessly, the platform handles large data sets, high user volumes, and multiple applications. With hybrid semantic and lexical indexing, machine learning models like Automatic Relevance Tuning (ART), and personalized ranking, as well as control over weighting factors and business rules in the query pipeline, Coveo continuously improves retrieval results, ensuring enterprise-wide AI performance that evolves with each user interaction.

Early Access Program Sees Impressive Results

Early Access Program customers saw impressive results. One Fortune 500 software organization that implemented Coveo’s Passage Retrieval API reported that in only 2 weeks they were able to improve article and passage retrieval accuracy by 22% over their in-house retrieval tool which led to a 73% improvement in generated answer accuracy of their internal GenAI chatbot.

“Integrating Coveo’s Passage Retrieval API has improved our ability to deliver highly customized AI solutions,” said Eric Immermann, Search and Content Practice Director at Perficient, a close System Integration partner of Coveo who tested the Passage Retrieval API during our Early Access Program. “From automating sales queries and enhancing global search experiences for our clients, to powering our own internal RFI generation tool, we’ve seen how better relevance in generative answering drives efficiency and business value. With Coveo’s unified hybrid index, we can improve answer relevance across various GenAI applications — making AI adoption faster, easier, and more cost-effective for us and our clients.”
